This part makes little sense to me for two reasons. 1) David Miller handles stable submission himself ( Documentation/networking/netdev-FAQ.txt ) 2) We are not supposed to make sure old kernels will compile with future compilers. That would need a lot of work and potential new bugs, not worth the time. Otherwise your patch looks fine really ;)
